WRITING-PEN.

SPECIFICATION forming part of Letters Patent No. 256,958, dated April25, 1882.

Application filed December 28, 1881. (Model) To all whom it may concern:

Be it known that I, EDWARD D. BLACK- WELL, of Montpelier, in the countyof Washington and State of Vermont, have invented a certain new anduseful Improvement in Writing-Pens,of which the following ima full,clear, and exact description.

The invention consists in a pen for writing purposes, constructed orprovided in the hollow or concave inner side of its body with a crosswall or partition, preferabh bowed and set inclining or shelving forwardon its inner face, but which may be otherwise arranged, and of anysuitable shape. This cross wall or partition, while it has otherfunctions or uses, is primaiily for the purpose of preventing the ink inthe pen from soiling the writers fingers, as hereinafter described.

The invention is applicable to all or most descriptions of pens, Wl houtregard to the material of which they are made, but. is more particularlydesigned for steel or other metal pens requiring holders for their use.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents an inner faee view of a pen having my inventionapplied, and Fig. 2 isa longitudinal section of the same on the line 00m in Fig.1.

The pen, which may be of any desired pattern, has the hollow or innerconcave side ol its body a divided by a cross wall or partition, I), atasuitable point in thelength ofthe body to prevent interference with thefit of the pen in a suitable holder, and to avoid impairing theelasticity or flexibility of the pen. This wall I) not merelystrengthens the pen and restrains it from splitting without encuinberingit or marring its beauty, but acts as a stop or dam to the ink containedwithin the pen from soiling the writers or users fingers. Thus, with theordinary construction of pen, it is oiten or almost invariably the casethat when a pen-holder with ink in the pen is laid down or placed behindthe ear the ink runs back out of the pen onto the holder, especiallywhen the latter is a rubber one, thereby causing the writers fingers tobe soiled with ink when taking up the pen again for use. This isobviated by my improvement, the cross wall or partition I) preventingthe ink from running back out of the pen when the. pen-holder istransposed,as described. (Jonsequentlytheink does not pass onto theholder to subsequently soil the writers fingers. To more ifl'ectunllyrestrain the ink from running back Out of the pen, as just referred to,it is prelerred to make the partition I) of a hol ow or bowed form onitsfiuze,and to set said faceincliningor shelving forward-that is,toward the point of the pen, from iheinteriorof the body of thelatterhus forming a guard or bucket to catch and hold any ink that mayrun back. Said wallor partition, however, which may either be formedwith the pen in the course of its manufacture or be subsequentlyinserted in and secured to the pen, may be of any other suitable shape,and be otherwise set or arranged.

Having thus fully described my invention, 1 claim as new and desire tosecure by Letters Patent- 1. An improved pen having a wall or partitionextending entirely across and rigidly attached to the inner concave sideof its body, substantially as shown and described, whereby the inkis'prevented from flowing back and soiling the fingers of the writer,and the pen strengthened'and prevented from splitting, as set forth.

. 2. A pen having the hollow or concaveinner side of its body providedwith across wall or partition of hollow form on its face andsctincliningor shelving toward the point of the pen from the interior ofthe body of the latter, whereby a bucket-shaped guard is formed withinsaid body to catch and hold any ink running back within it,substantially as herein set forth.
